@JRE I'm wanting to make a better DC tesla coil. But I'm having a hard time finding a tansistor, resistor and capacitor combination that will work for 50 VDC input. Do you have any part recommendations for me?
I'm also using the formulas and one of them is for voltage drop across a resistor. But I'm getting wrong answers. The schematic before said a 2.2kOhm resistor and it was powered by 9 VDC. That would mean 0.00409 volts are getting through. But that's so little voltage.
This is a perfect explanation that proves my research on different voltage breakdowns distances for a higher power input device v.s a lower power input device. This also proves my research again on why insulators breakdown even when rated higher than the output voltage. Take a look everyone. Theres something to learn from my research here.
@ScientistSmithYT That's 0.0040909090909 amperes, not volts.
The breakdown (the point at which the voltage is high enough for air to conduct) depends on the output voltage. Period. The input power doesn't change the voltage needed for breakdown.
The actual breakdown voltage of air depends on the air pressure and the voltage. The shape of the electrodes can change the "concentration" of the voltage difference so that arcs can more easily occur.
Big, rounded objects are less inclined to arc than small pointed ones. That's why all the high voltage equipment has smooth, round conductors and the terminals are big, smooth balls.
@ScientistSmithYT Remember our discussion about temperatures? Same thing here. When you go to claim that something basic and well known is wrong in physics, you'd better have your ducks in a row.
And I also am well aware of that too. There are a lot of variables in different scenarios. But if you have a set case the elemental principals can be proven as long as the scenario isnt changed.
Yes I do remember that. And this time I do have everything straight. I've been studying, experimenting and testing this for years now.
And this experiment (that gave is these values) was done on a limited power supply and then put on a sheet and then later put on a table. So everyone can look at it. There are many flaws I already see and I've tested those flaws and come up with very interesting results.
In society HV is looked at as deadly no matter what. And then scares people. Which then leaves people like me to do these experiments because we feel comfortable doing it to educate people and make new discoveries. There was a time where HV was studied a lot. But that hasn't happend a lot lately. So its time for more tests to be done.
Input power is only interesting to the breakdown insofar as it affects your circuit's ability to raise its output to the required output voltage, and to supply energy to maintain the arc. If you use a very weak input source and reach breakdown on the output, then the arc will be weak and will stop.
If you know what corona discharge is, the compare it to your "HV particle discharge."
I'll be honest with you. The HV project I want to make is going to output 12,000,000 volts. And I'm a little scared to do it. Because this project does have enough amperage to kill 100% of the time. There isn't a chance like there is with MOT's or NST's. But I'm going to do it to make a discovery that maybe we haven't made yet. And if I find out nothing was new, well I have something cool.
Ok, particle discharge is when tiny amounts of current can jump a medium given a certain gap. Corona discharge is when more current is flowing but not yet a complete plasma channel.
Either way they are both HV in relation to the insulator type and thickness.
The medium can be an insulator like plastic or an insulator such as air. Particle discharge is seen more often with insulation on wires.
As far as the input power goes. There are more factors that play an important role in that. But if all of them are set. Then tests can be done to again prove elemental principals.
@JRE There are a lot of things even small things not very many people know about without doing it. For the people who do, do this stuff they know even the smaller stuff effects things significantly.
As far as my project. I'm still thinking on whether I want to do it or not. Because if I make a mistake just 1. The math says I have 0% of surviving even if I made electrical contact for 1.2 milliseconds. And there's 100 milliseconds in 1 second. And That's fast. Its been something I've been thinking about for a while. And I've contacted a lot of HV linemen and they tell me they don't know or they don't have expertise in that high of a voltage. Even though they work on 1 million volt lines.
These 1 million volt workers generally fly in specialized helicopters and use metal clips to energize themselves to the voltage level. So theres not a volt potential. Then they use a pole to de-energize themselves when they unclip the line and fly away.
Yeah I've seen pictures of that incredible work of art.
Its a beauty.
What I need to know is what makes a diode?
What is inside a diode that makes it work. I've seen pictures and other 3D designs of them. But what chemicals make it work?
That is a very extremely important piece of information I've been searching for for a long time.
@JRE With my project. I only have 1 chance this time if I go through with it. The electrical energy has more than enough juice to explode 10 watermelons. I have no room for error. That's it. If I make it right and it works perfectly and produces the voltage I want. It'll be an amazing feat for me and progress. It will also open up many other doors and opportunities that can allow the progression in my studies.
@JRE When you get back could you help me find out what a diode has inside it? I've looked every where.
@JRE Its night time here, so I'll be waking up in about 10 or so hours from now. But if you can leave messages about it I'll definitely see it as I wake up.
Or, you know, buy high voltage diodes with known, guaranteed performance (forward voltage, peak reverse voltage, forward current, leakage current, switching time, switching recovery time, yada, yada, yada.)
@JRE Where would I buy those massive diodes then? Because 30 kV diodes won't do.
The highest diode voltage is 30 kV as far as I know. There is such thing as 35 kV diodes but those are looked down upon. I dont know why they are but they are.
@JRE One question I have is I could make a diode pack then just use more stages and more diodes than what I want to use. But lets say I need a 60kV diode array. And the stage is around 50 kV. I could combine the diodes either in series or parallel. But what array changes what?
Like does the parallel change the amperage or voltage tolerance? And does series change the voltage or amperage tolerance?
You can put diodes in series to get a higher reverse voltage. You can put them in parallel for more current capability. There are pitfalls to doing it, though. Do it wrong and the little bastards will blow up on you.
There were questions there about multi-junction solar cells, but I guess people here could ask questions about semi-conductors and next-after-silicon materials like graphene and GaAs for next-generation computer chips.
Actually it looks like someone already asked something about semiconductors there.
